After pondering his image for a moment, Liszt began considering the issue of fusion training with the Invisible Dragon.
The Invisible Dragon was not an Elemental Dragon. Though it could hide within the boundaries of matter and become invisible, it could not transform into an element and merge into Liszt's body. Thus, many training skills suitable for Rio were unsuitable for the Invisible Dragon. Moreover, its dragon breath was a white mist formed of spatial magic.
Wherever the white mist passed, it could shatter any substance. It was a tremendously powerful offensive move.
Clearly, this white-mist dragon breath could not be used to train Dragon's Breath Body Tempering.
There was little to say about Dragon Force Focus. Basically every dragon knight knew the skill, guiding the dragon to concentrate all its strength into a single beam rather than dispersing it. The Invisible Dragon could also train Dragonheart Telegraph Code, though it had to learn its patterns before it could communicate with Liszt across a distance.
Dragon-Blood Infection naturally went without saying. The Hillside Cows and Estuary Pigs on Black Horse Island were all masterpieces of the Invisible Dragon's infection.
Dragon Rider Resonance was even more basic—nothing worth mentioning.
The problem now was that some issues had arisen when Liszt attempted to fuse and cast his secret battle aura techniques with the Invisible Dragon. Spiral Rotation, Aura Attenuation, and Magic Eye were all difficult to operate through the Invisible Dragon. The supportive effects of Spiral Rotation and Aura Attenuation were weak enough to ignore.
Magic Eye alone was Liszt's signature skill, and it absolutely had to be made to work on the Invisible Dragon—since the Invisible Dragon could freely pass through space, with Magic Eye's assistance, perhaps even the essence of the world itself would fall into Liszt's grasp.
